MACHINE FOR REINFORCING- HOSE.

Specification of Letters Patent.

Application filed December 9 1911; Serial No. 664,870.

To all whom it mag concern:

Be it known that I, SAMUEL J. SILL, a citizen of the United States, anda resident of Buffalo, county of Erie, and'State of New York, haveinvented certain new and useful Improvements in Machines for ReinforcingHose, of which I do declare the following to be a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

Figure 1- is a view in front elevation, parts being shown in verticalsection, of a machine embodying my invention. Fig. 2 is a plan view.Fig. 3 is a view in vertical section on line 33 of Fig. 1. Fig. 4 is aview in vertical section on line 4-4 of Fig. 1. Fig. 5 is a view invertical section on line 55 of Fig. 1. Fig. 6 is a view in verticalsection on line 66 of Fig. 1. Fig. 7 is an .enlarged view in centralvertical section through a section of hose mounted upon a mandrel andillustrating the purposes of my invention.

In the manufacture of certain types of rubber hose for railway trainservice and more particularly in the manufacture of the hose sectionscoupling the locomotive and tender, it is desirable to reinforce thehose by'winding about the same a coil of wire in order to strengthen andprevent the collapsing of the hose.

In Fig. 7 of the drawing is shown a section of hose A mounted upon atubular mandrel B, this hose section-being formed in the followingmanner: An inner tube a of rubber is first wound with a. layer of ducka. The mandrel B with the inner tube a and duck layer a is then woundwith a coil of reinforcing wire C, as indicated in Fig. 7 of thedrawing. Two plies of duck a and a ply of rubber a? are then woundaround the hose section. A temporary wrapper of cloth will then be woundabout the hose and, finally, a coil of rope D will be tightly wound'about the hose to drawits outer plies snugly in between the coils of thewire C. After the vulcanization of the hose has been effected, the ropeD and the temporary cloth wrapper (not shown) will be removed.

The object of my invention is to provide a simple and effective meanswhereby. the

standards 9, 10 and 11.

a bracket 12 in which is journaled the outer end of the maindrive shaft'13. The inner end of the drive shaft 13 is journaled in suitablebearings formed in the lower portion of the standards 10 and 11. Uponthe -main drive shaft 13 is mounted a drive pulley 14 having connectedthereto a suitablefriction clutch member 15, thc arms 16 of this clutchmember being arranged to be engaged by the cone sleeve 17 that is keyed..to, and slidably inounted upon the main drive shaft 13. The cone sleeve17 is formed with a peripheral groove to receive the studs '18 thatproject inward from the yokeshaped portion 19 of the clutch lever 20.

This clutch lever 20 is shown as pivotally connected, as at 21, to astud or offset 22 projecting from the end of the main frame of themachine (see Fig. 4). The friction clutch, its cone sleeve and theclutch lever are of familiar construction and will be readily understoodby those conversant with this class of devices. Upon .the main driveshaft 13 and between the standards 10 and 11 are keyed the large gearwheel 25 and the smaller gear Wheel 26. These gear 'wheels 25 and 26mesh respectively with the gear wheels 27 and 28 that are 'looselymounted upon themandrel shaft 29 journaled in the upper ends of thestandards 10 and 11. Upon the shaft 29 and between the gear wheels 27and 28 is slidably mounted a friction clutch 30, this clutch-beingunited to the shaft 29 by splines 31 (see Figs. 1 and 5) and having atits opposite ends the conic'al friction surfaces 32 and 33 adapted toengage respectively with corresponding conical' surfaces 27 and 28 ofthe gear wheels 27 and 28. The clutch 30 is formed centrally with aperipheral groove within which loosely fits a clutch ring 35, thisPatented Aug. 10,1915.

as shown at 43 (see Fig. A collar 44.

at the rear end of the shaft 40 holds it in position within its bearing.Upon the opposite end of the shaft 40 is fixed a sleeve 45 from whichdepends an arm 16, and the end .47 of this arm enters a peripheral slotof a shifting cam 51 that is fixed'to the shaft 52 and is journaled insuitable bearings 53 and 54: on top of the bed plate 8 of the machineframe (see Figs. 1 and 2). To the shaft 52 are fixed, as by set screws55, suitable handles (one or more) 56 whereby the shaft 52 maybeconveniently operated, so as to throw the clutch 30 into engagementwith either of the gear wheels 27 and 28 or to move the clutch to thecentral and idle position shown in Fig. 1 of the drawlhe inner end ofthe shaft 29 is provided with a suitable part, as, for example, aconical head 60 to engage one end of the mandrel B (see Fig; 7), whereonis mounted the section of hose to be wrapped by the wire,

and, as shown, the conical head 60 is provided with a rib 61 adapted toenter the slot b in the end of the mandrel to insure the revolution ofthe mandrel. The top of the standard 9 (see Figs. 1, 2 and 6) is shownas chambered to receive an adjustable head block 65 on the stem 66 ofwhich is revolubly mounted the'conical head 67, adapted to enter one endof the mandrel B. The head block 65 has its outer end threaded toreceive an adjusting screw 68 that is provided 'at its outer end with ahand wheel 69. The screw 68 passes through a hole formed in a cap 70that is screw threaded to engage a correspondingly threaded portion 71formed at the top of the standard 9 and the shaft of the screw 68 isalso provided with an annular flange or offset 72 to hold it againstdisplacement. By means of the adjustable head block 65 the conical head67 may be readily retracted when the mandrel with the hose sectionthereon is to be placed upon or withdrawn from the machine.

From the foregoing description it will be seen that when the clutch 30is in the idle position shown in Fig. 1, no revolution will be impartedto the shaft 29, although the gear wheels 27 and 28 are being drivenfrom the main drive shaft 13. If the clutch 30 be moved to the right(see Fig. 1), so as to 'cause its friction surface 33 to engage with thecorresponding friction surface 28 of the gear wheel 28, revolution willbe imparted from the main drive shaft 13 to the mandrel driving shaft 29through the small gear Wheel 26, the large gear wheel 28 and the clutch30, and this will cause the mandrel driving shaft 29 to revolve at arelatively slow speed. This slow speed of the mandrel driving shaft willbe preferably eniployed as the Wrapping of the reinforcing Wire aboutthe hose section is begun; but

when the wrapping of the reinforcing wire has been accurately started atthe slow speed, the clutch 30 will be shifted to the left so as tocauseits friction surface 32 to complete it, at a higher speed. The shiftingof the clutch 30 can be readily effected by the operator standing at thefront of the machine through the medium of the handles 56 on the shaft52, as theturning of the shaft 52 causes the shifter cam 51 to actuatethe arm 46 and throw .the'clutoh yoke 38 in either direction.

Between the standards 9 and 10 extends a shaft 80, the ends of which arefixed, as by set screws 81, (see Figs. 1 and 2) in suitable socketsformed in the standards. Upon this shaft is mounted in manner free toslide, the wire laying arm 82.' This wire laying arm 82 is formed toextend up and over the mandrel in the hose section when they are inposition to be wound with the reinforcing wire, and the front end ofthis arm 82 is furnished with a suitable handle 83 that may be readilygrasped by the operator standing at the front of the machine. From thearm 82 depends a wire support or guide 84 (see Figs. 1 and 3) thatconsists preferably of a steel hook, the screw threaded end of whichpasses up through the arm 82 and is held in position by means of a nut85. The lower end of the wire laying arm 82 is shown as extendingdownward and rearward from the shaft 80 and is provided with asemi-cylindrical portion 86 face withscrew threads corresponding to thethreads of the screw shaft 871 (see Figs,

1, 2 and 3) that extends fromend to end of the machine and is journaledin suitable bearings at the base of the several standards 9, 10 and 11.v shaft 87 is to advance the wire laying arm 82 and cause the wire tobe-coiled v uniformly about the surface of the hose-section, 'as themandrel carrying this section is revolved by the mechanism hereinbeforedescribed.

In order to permit the pinion 88and the gear wheel 29 to be replacedwith a pinion The purpose of this screw and gear wheel of diflerentdiameter, when it is desired to vary the relative speed of revolutionimparted by the gear wheel 29 to the pinion 88, I prefer to mount theidler pinion 89 in a swinging arm 90 as next de scribed. This swingingarm 90 is pivoted, as at 91, to a stud projecting from one side of thestandard 11 and the arm 90 is formed with a curved slot 92 through whichpasses the reduced threaded end of a stud 93 that 'is provided with anut 94 that enables the arm to be set at any desired position. The upperportion of the arm 90 isformed with a long slot 95 through which passesa bolt 96 on which is revolubly mounted the idler pinion 89. The bolt 96has a square head that sets within a groove formedon one side of thepivoted arm, this groove being. indicated by dotted lines in Fig. 4 ofthe drawings. WVhen it is desired to vary the speed of revolutionimparted by the gear wheel 29 to the pinion, 88, as, for example,

to impart a slowerspeed of revolution to the screw shaft 87, theoperatorwill remove the pinion 88 and-the gear wheel 29, will thenloosen the screw 94 so as to permit the swinging arm 90 to be turneddownward and will then substitute for the pinion 88 and the gear wheel29 the pinion and gear wheel of required diameter. Having done this, theoperator will then swing upward the arm 90 to bring the idler pinion 89into mesh with the substituted pinion and gear wheel and will adjust thestud that carries the idler pinion 89 in the slot 95 and will reset thenut 94 that positions the swinging arm 90- so as to hold the idlerpinion in engagement with the substituted pinion and gear wheel.

From the foregoing description it will be seen that when a hose sectionis to be wrapped with reinforcing wire 0, the mandrel B (see Fig; 7)will be placed in position between the conical heads and 67, asindicated by dotted lines in Fig. 1. of the drawings. The operator willthen lay one end of the wire C (see dotted line in Fig. 3) upon the hosesection adjacent its end and will fasten this end of the wire preferablyby means of a piece of rubber tape, so as to hold it 'as the windingoperation is begun,

The operator will then shift the clutch 30 so as to cause the mandreldriving shaft 29 to be initially driven through the medium of the largergear wheel 28 which Wlll cause a slow revolution to be given to themandrel,

and the hose section thereon. It will be understood, of course, that asrevolutionds thus imparted to the mandrel B, the W1Ie laying arm 82, byreason of the engagement of the threaded portion 86 with the screw shaft87 will be gradually advanced from left to right, so as to lay the wireC in uniform coils upon the surface of the hose. As soon as the initialwinding of the wireC has ing of the wire C about the hose can be rapidlyand quicklycompleted, and when the winding of the wire around a hose section is finished, the operator will secure the end of-the wire by meansof rubber tape and the mandrel will then be removed from the machine, sothat the additional layers of duck and rubber may be applied.Subsequently, the rope D (see Fig. 7) may be wound upon the outersurface of the hose to squeeze the outermost layers between the coils ofwire C, and after the rope D has been thus wound, atemporary wrapper ofcloth will be Wound around the hose and" it will be subjected to thevulcanizing operation. j

When a section of hose has been wrapped with wire, the operator, bylifting the handle 83 of the wire laying arm 82 will cause the threadedend 86 of the arm 82 to be disengaged from the screw shaft 87 and thearm 82 can then be quickly slid back into posi-' tion (as shown in Fig.1), to again begin the winding operation.

My invention presents an exceedingly simple and effective machine foraccomplishing the winding of the reinforcing wire about the hosesections and while I have v described what I regard the preferred formof my invention, it will be understood. that its precise details may bevaried by the skilled mechanic without departing from the spirit of theinvention. Thus, while what I have termed the wire laying arm 82 affordsa most effective means for carrying the wire C during the windingoperation, it is obspeeds to the mandrel driving shaft from the maindrive shaft, it is obvious that other forms of variable speed mechanismmight be employed without departing from the. scope of the invention.
